Abstract
Description
Die Erfindung betrifft einen Kühlkörper mit einem Wärmeauf nahmebereich, der durch eine Basisplatte gebildet ist und der in Kontakt mit einem zu kühlenden Bauteil steht, und einem Wärmeabgabebereich, der sich an den Wärmeaufnahmebereich an schließt, zur Abgabe von Wärme an die Umgebung des Kühlkör pers.The invention relates to a heat sink with a heat area, which is formed by a base plate and the is in contact with a component to be cooled, and one Heat dissipation area that adheres to the heat absorption area closes to give off heat to the surroundings of the heat sink pers.
Es ist eine große Vielfalt von Kühlkörpern bekannt. Klein kühlkörper sind an die genormten Gehäuse von beispielsweise Halbleiterbauelementen angepaßt und können einfach aufge steckt werden. Zur Verbesserung des Wärmeübergangs zwischen den Halbleiterbauelementen und dem Kühlkörper ist es bekannt, sogenannte Wärmeleitpaste zu verwenden. Für Großkühlkörper werden vorwiegen fertiggezogene Aluminium-Profile benutzt. Verschiedene Ausführungen von Kühlkörpern sind beispielsweise aus "Nührmann, Dieter: Das große Werkbuch Elektronik, Teil A, Francis-Verlag, München 1998" bekannt.A wide variety of heat sinks are known. Small heat sinks are adapted to the standardized housing of, for example, semiconductor components and can simply be plugged on. To improve the heat transfer between the semiconductor components and the heat sink, it is known to use so-called thermal paste. Pre-drawn aluminum profiles are mainly used for large heat sinks. Various designs of heat sinks are known, for example, from "Nührmann, Dieter: The Great Workbook Electronics, Part A, Francis Verlag, Munich 1998 ".
Bei Mikroprozessoren hängt die erzeugte Wärme in hohem Maß von der verwendeten Taktfrequenz ab. Je höher die Taktfre quenz ist, desto größer ist die Verlustleidtung und damit Wärme, die an die Umgebung abgeführt werden muß. Durch Fort schritte in der Halbleitertechnologie ist die Taktfrequenz mittlerweile so hoch, daß bisher bekannte Kühlkörper in der üblichen Größe nicht mehr ausreichen, selbst wenn Lüfter zur Zwangskühlung eingesetzt werden. Die einzige Möglichkeit, dennoch eine ausreichende Kühlung sicher zu stellen, ist da her, die Kühlkörper weiter zu vergrößern, was aber aus ande ren konstruktiven und technischen Gründen nicht wünschenswert oder nicht möglich ist.The heat generated in microprocessors depends to a large extent depends on the clock frequency used. The higher the clock frequency quenz is, the greater the loss suffering and thus Heat that must be dissipated to the environment. By fort Steps in semiconductor technology is the clock frequency meanwhile so high that previously known heat sinks in the usual size is no longer sufficient, even if fans are used Forced cooling can be used. The only way nevertheless there is sufficient cooling to ensure forth to enlarge the heat sink further, but what else ren constructive and technical reasons not desirable or is not possible.
Aufgabe der Erfindung ist es daher, einen Kühlkörper anzuge ben, der eine verbesserte Wärmeabgabefähigkeit besitzt, ohne deswegen größere Abmessungen aufzuweisen. Außerdem soll das Gewicht des Kühlkörpers gering sein.The object of the invention is therefore to provide a heat sink ben who has an improved heat dissipation ability without therefore to have larger dimensions. In addition, that should Weight of the heat sink should be low.
Diese Aufgabe wird erfindungsgemäß durch einen Kühlkörper der eingangs genannten Art gelöst, der dadurch gekennzeichnet ist, daß der Wärmeabgabebereich durch einen offenporigen Me tallschaumkörper gebildet ist.This object is achieved by a heat sink solved type mentioned, characterized in that is that the heat dissipation area by an open-pore Me tall foam body is formed.
Durch die Basisplatte ist gewährleistet, daß ein guter Wärme übergang von einem zu kühlenden Bauteil auf den Kühlkörper erfolgt. Optimiert ist bei den erfindungsgemäßen Kühlkörpern hingegen der Wärmeabgabebereich. Der offenporige Metallschaum hat naturgemäß eine wesentlich größere Oberfläche als die Kühlrippen bekannter Kühlkörper. Dadurch ist die Vorausset zung gegeben, eine größere Wärmemenge an die Umgebung abzuge ben. Trotzdem bleibt es wichtig, daß das verwendete Material auch gute Wärmeleiteigenschaften aufweist. Daher ist es vor teilhaft, einen Aluminiumwerkstoff zu verwenden, da Aluminium sehr gute Wärmeleiteigenschaften aufweist. Weiterhin ist es für die Kühleigenschaften wichtig, daß eine Luftzirkulation zum Abtransport der Wärme ermöglicht ist. Vorteilhaft erweist es sich diesbezüglich, wenn die Dichte des Metallschaums von der Basisplatte zu der von der Basisplatte abgewandten Seite des Wärmeabgabebereichs abnimmt. Dadurch ist sichergestellt, daß der Metallschaum die Wärme, die von dem zu kühlenden Bau element auf die Basisplatte übertragen wird, von dieser an den Metallschaumkörper weitergeleitet wird und der Metall schaumkörper diese auch aufnehmen kann. In den äußeren Be reich ist es dagegen eher wichtig, daß die Möglichkeiten zur Luftzirkulation möglichst gut sind, die Poren also größer sind beziehungsweise die Dichte kleiner ist. Die Gewichtser sparnis gegenüber einem Kühlkörper konventioneller Bauart be trägt bei gleicher Kühlleistung 80-90%.The base plate ensures that good heat transition from a component to be cooled to the heat sink he follows. The heat sinks according to the invention are optimized however, the heat dissipation area. The open-pore metal foam naturally has a much larger surface than that Cooling fins of known heat sinks. This is the prerequisite given a larger amount of heat to the environment ben. Nevertheless, it remains important that the material used also has good thermal conductivity. Therefore it is before partial to use an aluminum material because aluminum has very good thermal conductivity. Furthermore it is important for the cooling properties that air circulation to remove the heat is made possible. Proves advantageous it is in this regard if the density of the metal foam of the base plate to the side facing away from the base plate of the heat dissipation area decreases. This ensures that the metal foam the heat from the building to be cooled element is transferred to the base plate from there on the metal foam body is passed on and the metal foam body can also accommodate this. In the outer Be rich it is rather important that the possibilities for Air circulation is as good as possible, so the pores are larger or the density is smaller. The weights savings compared to a conventional heat sink carries 80-90% with the same cooling capacity.
Die Erfindung wird nachfolgend anhand eines Ausführungsbei spieles näher erläutert. Die Figur zeigt dabei ein Halbleiterbauelement, auf das ein erfindungsgemäßer Kühlkörper auf gesetzt ist.The invention is illustrated below with the aid of an embodiment game explained in more detail. The figure shows a semiconductor component, on which a heat sink according to the invention is set.
Das zu kühlende Bauelement in der Figur ist ein Halbleiter-IC 1. Dieses ist schematisch dargestellt und besitzt nur wenige Anschlußpins 6. In der Regel wird dies ein Prozessor sein, der wesentlich mehr Anschlüsse aufweist. Die Bedeutung der Kühlung hängt aber natürlich nicht von der Anzahl der An schlußpins 6 ab, sondern von der in dem Bauelement 1 erzeug ten Wärme. Bei Prozessoren ist sie in der Regel abhängig von der Taktfrequenz. Bei Leistungshalbleitern, die ebenfalls ge kühlt werden müssen, ist dagegen die Höhe des Stromes für die Größe der erzeugten Verlustleistung ausschlaggebend. Auf die ses Halbleiter-Bauelement 1 ist ein Kühlkörper 7 mit einer Basisplatte 2 aufgesetzt. Zur Befestigung des Kühlkörpers 7 auf dem Halbleiter-Bauelement 1 sind verschiedene Techniken bekannt. Eine Technik besteht darin, den Kühlkörper 7 auf dem Halbleiter-Bauelement 1 festzuklammern. In einer anderen Mög lichkeit wird der Kühlkörper 7 auf dem Halbleiter-Bauelement 1 festgeklebt. Insbesondere finden dabei wärmeleitfähige Kle ber Verwendung. Die Verbindung der Basisplatte 2 des Kühlkör pers 7 mit dem Halbleiter-Bauelement 1 erfolgt jedenfalls nicht anders, als vom Stand der Technik her bekannt ist. Auf der von dem Halbleiter-Bauelement 1 abgewandten Seite der Ba sisplatte 2 ist ein Metallschaumkörper 3 mit einer offenzel ligen Honigwabenstruktur als Wärmeabgabebereich vorgesehen. Nahe der Basisplatte 2 befindet sich ein Bereich 4 des Me tallschaumkörpers 3, in dem dessen Dichte relativ groß ist. Die Wärmeleitung von der Basisplatte 2 in den unteren Metall schaumkörperbereich 4 ist daher unproblematisch. Allerdings ist die Konvektion, durch die Wärme an die Umgebung des Kühl körpers 7 abgegeben werden kann, relativ gering. Um eine bes sere Konvektion zu erreichen, verringert sich die Dichte mit zunehmendem Abstand von der Basisplatte 2. Dadurch wird in einem von der Basisplatte beabstandeten Metallschaumkörperbe reich 5 eine freie Konvektion ermöglicht. The component to be cooled in the figure is a semiconductor IC 1 . This is shown schematically and has only a few connection pins 6 . As a rule, this will be a processor that has significantly more connections. The importance of cooling, of course, does not depend on the number of connection pins 6 , but on the heat generated in component 1 . For processors, it is usually dependent on the clock frequency. In the case of power semiconductors, which also have to be cooled, the amount of current is decisive for the size of the power loss generated. A heat sink 7 with a base plate 2 is placed on the semiconductor component 1 . Various techniques are known for fastening the heat sink 7 to the semiconductor component 1 . One technique is to clamp the heat sink 7 on the semiconductor component 1 . In another possibility, the heat sink 7 is glued to the semiconductor device 1 . In particular, thermally conductive adhesives are used. The connection of the base plate 2 of the Kühlkör pers 7 with the semiconductor device 1 is in any case no different from what is known from the prior art. On the side facing away from the semiconductor component 1 of the base plate 2 , a metal foam body 3 with an open-cell honeycomb structure is provided as the heat dissipation area. Near the base plate 2 is an area 4 of the tall foam body 3 in which the density thereof is relatively large. The heat conduction from the base plate 2 into the lower metal foam body region 4 is therefore unproblematic. However, the convection through which heat can be given off to the surroundings of the cooling body 7 is relatively low. In order to achieve better convection, the density decreases with increasing distance from the base plate 2 . This allows free convection in a metal foam body region 5 spaced from the base plate.
Die Kühlung ist wesentlich verbessert, wenn sich der Kühlkör per 7 beziehungsweise dessen Metallschaumkörper 3 sich in ei nem Luftstrom befindet, wie dies auch beim Stand der Technik häufig der Fall ist.The cooling is significantly improved if the heat sink by 7 or its metal foam body 3 is in an air flow, as is often the case in the prior art.
Gegenüber Kühlkörpern des Standes der Technik weist ein er findungsgemäßer Kühlkörper 7 ein kleineres Gewicht auf. Auch ist vorteilhaft, daß dem Metallschaumkörper 3 eine beliebige Form gegeben werden kann. Dadurch können auch kleinere Bau räume genutzt werden.Compared to heat sinks of the prior art, he heat sink 7 according to the invention has a smaller weight. It is also advantageous that the metal foam body 3 can be given any shape. This means that even smaller spaces can be used.
Als Material für den Metallschaum wurde Aluminium angegeben. Es ist aber auch denkbar, statt dessen Kupfer, Eisen oder Zinn zu verwenden.Aluminum was specified as the material for the metal foam. But it is also conceivable, instead of copper, iron or To use tin.
